BUTTER-SEPARATOR.

Specification of Letters Patent.

To all whom it may concern.'

Be it known that I, GEORGE W. WINTERS, a citizen of the United States,residing at De Queen, in the county of Sevier and State of Arkansas,have invented certain new and useful Improvements in Butter-Separators,of which the following is a specification.

This invention appertains to butter manueffecting separation of thebutter globules or fat from the milk, the purpose being to devise amechanism operating by centrifugal action to throw the cream outwardagainst the sides of a receptacle with such force and velocity as toeffect rapid separation and collection of the butter particles.

The invention consists of novel actuating means adapted to be shiftedfrom one posi* tion to another with reference to the receptacle to admitof the dasher operating either at a central point or to one side of thecenter according to the result to be attained.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction and the'meansfor effecting the result, reference is to be had to the followingdescription and accompanying drawings.

While the invention may be adapted to different forms and conditions bychanges in the structure and minor ,details without departing from thespirit or essential features thereof, still the preferred embodiment isshown in the accompanying drawings, in which:

Figure 1 is a perspective view of a butter separating mechanismembodying the invention. Fig. 2 is a vertical central section thereof.Fig. 3 is a detail perspective view of the lower portion of thereceptacle, the dasher and operating mechanism being removed. Fig. 4 isa perspective view showing the operating mechanism occupying a positionfor driving the dasher when arranged at a central point. Fig. 5 is adetail perspective view of the frame of the operating mechanism.

Corresponding and like parts are referred to in the followin descriptionand indicated in all the views of the drawings by the same referencecharacters.

The receptacle 1 for receiving the milk or cream to be churned ispreferably of cylindrical form and its bottom upon the inner side ismade rounding or sloping to more receive the lower end of the frame 3which is' correspondingly tapered to insure a tight fit of the frame inthe socket when the parts are assembled. A hand grip 4 is provided atone side of the receptacle near the bottom for convenience when tiltingthe receptacle to pour off the contents. A bail 5 applied to thereceptacle enables the same to be conveniently carried or handled.

The cover 6 for closing the upper end of the receptacle is preferably ofconical form and is provided at its apeX with an opening 7 and at oneside with a notch 8, both providing for the passage of the dasher shaft9 according to its position. A handle 10 is secured to the centralportion of' the cover and is pro vided ata middle point with an opening11 through which the dasher shaft 9 is adapted to pass and at one sidewith a socket 12 corresponding in form to the socket 2 and adapted toreceive the frame 3 when the latter is arranged to operate the dasherwhen occupying a central position within the receptacle. A side portionof the cover is formed with a series of small openings 13 providing ineffect a strainer to separate the butter from the liquid when pouringthe same from the receptacle after the churning operation.

The agitator, dasher or churning device 14 is formed of a plate having aconical form and provided at its sides with crimps forming flights orwings whichengage with the milk or cream in the operation of the machineand impart a whirling motion thereto. The dasher 14 is preferablyconstructed of a sheet metal disk crimped or fiuted about a centralpoint, thereby givingto the device a conical form and providing theflights 15 which are essential to engage with the milk or cream and setthe same in motion. The crimps or iiights 15 increase in depth and widthfrom a central point towards the upper outer edge' of the dasher and thesides thereof are formed with openings 16 to provide for ingress andegress of the cream or contents of the receptacle in the operation ofthe machine. When the dasher is set in motion, the flights 15 engagewith the cream and direct the same around in a circular path, producinga vortex since the liquid mass is caused to whirl. The upper portion ofthe mass is thrown outward by centrifugal action of the flights, therebydashing the mass against the sides of the receptacle and the vacuum thuscreated produces a suction at the vortex, thereby causingA the milk orcream 'to enter at the lower end or apex of the dasher. It will thus beseen that the liquid mass receives a tliree-fold movement, the one in acircular direction, the second outward against the sides of thereceptacle, and th'e third away from said sides or towards the axis ofrotation of the dasher. These two forces, namely, the centrifugal andthe centripetal action, produce a circulatory movement of the mass aboutat a right angle to its rotation, with the dasher about its shaft 9 asan axis.

When the dasher is arranged to operate with its major portion to oneside of the vertical or longitudinal axis of the receptacle, there is atendency to throw the mass more to one side of the receptacle than tothe other, and this is advantageous in quick churning or separation ofthe butter particles, but should there be a tendency of the cream torise, the dasher is arranged centrally of the receptacle, therebyretarding the rising action of the cream.,` this being shown in Fig. 4.1t is observed that the crirnps or flights 15 are of V-form and theopenings in one side thereof are in excess of the openings in theopposite side, the latter being arranged to the front with reference tothe direction of krotation and the side having the greater number ofopenings being arranged to the rear with reference to the direction ofrotation of the d asher. The d asher is reinforced at the apex in orderto provide a substantial and firm connection between it and the dashershaft.

r1`he frame 3 supporting the operating mechanism is deflected betweenits ends, the lower portion being tapered to fit snugly within either ofthe sockets 2 or 12 and the upper portion having bearings 17 and 18 inwhich a hollow shaft 19 is mounted and in which the dasher shaft 9 isdisplayed and secured in the adjusted position by means of a set screw20. The upper bearing 17 is chainbered upon one side to form a housingin which is fitted a pinion 21, the same being secured to the hollowshaft 19 between the separate portions of said bearing 17. The protectedside of the bearing 17 faces inward or towardv the dasher shaft 9 toprevent any oil passing from the pinion 21 to said dasher shaft. Aspindle 22 projects outward from the lower bearing 18 and receives adrive gear 23 which is mounted thereon and meshes with the pinion 21,said drive gear being provided with a crank handle 24 to admit ofoperating the machine by hand` The milk or cream to be cliurned isplaced in the receptacle 1 which is closed by means of the cover 6. Theframe 3 with the operating mechanism may be fitted'to either the socket2 or the socket 12 and the dasher shaft 9, after being slipped into thehollow shaft 19 and secured therein at the adjusted position,

is rotated by the mechanism herein disclosed. `When the dasher occupiesa central position,

its shaft 9 passes through the opening 7 of the cover and the opening 11of the handle 10.

Then the frame 3 is fitted in the socket 2, the v dasher 9 passesthrough the notch 8 in the side of the cover and its lower end is fittedin a guide 25 applied to the bottom of the receptacle and of V-form,thereby steadying and fixing the position ofthe dasher which isessential because of the unequal distribution of the load thereonresulting from the throwing of the mass in thereceptacle more to oneside thereof than the other.

The dasher may be adjusted to any level within the receptacle by movingthe shaft 9 in the hollow shaft 19 and securing-it in the adjustedposition by means of the set screw 2.

As the dasher isrotat'ed, a whirling motion is imparted to the milk orcream, with the result that a vortex is created, the upper portion ofthe mass being thrown outward and the lower portion drawn inward. Inorder to increase the agitation, a rib 26 extends along the inner sideof the receptacle 1 and forms a brake bar against which the mass isdashed, thereby assisting materially in the separation or churningoperation.

Having thus described the invention, what is claimed as new is:

1. A rotary dasher for the purpose specified formed of a disk of sheetmaterial crimped about a central point to provide a series of V-shapedflights and to give to the dasher an approximately conical forni, saidflights having openings in opposite sides, the openings in one sidebeing in excess of those in the other side.

2. In a machine of the character set forth, the combination of areceptacle having a socket, a frame removably fitted in the socket andhaving bearings and an offstanding spindle, a hollow shaft mounted inbearings and provided with a pinion, a drive gear mounted upon saidspindle and in mesh with said pinion, and a dasher having its shaftadjustable in the aforesaid hollow shaft adapted to be secured thereinat an adjusted position.

3. A machine of the character specified, comprising a receptacle havinga socket upon its side near its upper end, a cover having a centralopening, a handle fitted to the cover and having an opening in line withthe central opening formed in said cover and provided at one side with asocket corresponding 'to the socket of the receptacle, a frame adaptedto be fitted in either one of said sockets and provided with operatingmechanism,

frame and passing through the receptacle at an inclination and havingits lower end fitted in the aforesaid guide, the parts being arranged tooperate substantially in the manner specified.

In testimony whereof I affix my signature in presence of two witnesses.
